I can't remember if Kiefer ever said anything about taking a multivitamin while on CNS. I ask this because on one of the last podcast he put out, he or rocky, recommended a type II diabetic maybe to go up to 3 weeks before a carb nite if they had high BF%. If I am going that long I know I would be missing out on some vitamin somewheres. I was thinking that a multi with my coffee in the morning would do it.
